Abstract
Background and objective
Pityriasis rosea (PR), a common skin disease in young adults, may adversely affects the course of pregnancy and the unborn child.
Patients and methods
Data from forty‐six pregnant women with PR seen in the dermatological university clinic between 2003 and 2018 were analyzed and compared with patient data (n = 53) from previously published studies to determine the incidence and risk factors for an unfavorable pregnancy outcome after PR infection.
Results
Unfavorable pregnancy outcomes (defined as miscarriage, preterm delivery before week 37 of gestation, or birth weight < 2,500 g) were significantly less frequent in our study population than in a pooled cohort obtained from previously published studies (10.9 % vs. 39.6 %; P = 0.0012). Analysis of pooled data from our study and from previous studies revealed that the week of pregnancy at onset of PR was inversely associated with an unfavorable outcome (odds ratio [OR] = 0.937; 95 % CI 0.883 to 0.993). In addition, duration of PR (OR = 1.432; 95 % CI 1.129 to 1.827), additional extracutaneous symptoms (OR = 4.112; 95 % CI 1.580 to 10.23), and widespread rash distribution (OR 5.203, 95 % CI 1.702 to 14.89) were directly associated with unfavorable outcome.
Conclusion
In most cases, PR does not influence pregnancy or birth outcomes.
